Abstract
A radiofrequency identification tag has a semiconductor chip with radio frequency circuit, logic, memory circuits, and further includes an antenna that is mounted on a substrate. The antenna may be used by the chip to modulate an incident RF signal to transfer information to a base station. The antenna comprises one or more lengths of thin wire that are connected directly to the chip by means of wire bonding. The chip and antenna combination can be sealed with an organic film covering.
